Ronin DApps Integration

Welcome to MapNode Extension Wallet Developer Guide. This documentation contains guides for developers to get started developing on MapNode Extension Wallet.‌

To detect MapNode Extension with Ronin
To detect whether your browser is running MapNode Extension, please use:
if(window.MapNode || window.ethereum || window.ethereum?.isMapNode){
    console.log('MapNode Extension is installed!');
}
Notice: MapNode Extension Testnet is under development and not available now. The MapNode Extension on Ethereum JavaScript provider API is specified by EIP-1193. Support window.ethereum only and removal window.web3
To connect MapNode Extension Wallet
To connect MapNode Extension means to access the user's [blockchain - like Ethereum] account(s).
// Connect & get accounts
window.ethereum.request({method: 'eth_accounts'});
// Alias for connection
window.ethereum.request({method: 'eth_requestAccounts'});​
//Check if dapp connected
window.ethereum.isConnected();
To disconnect MapNode Extension Wallet
To disconnect MapNode Extension, please use:
window.ethereum.disconnect()
To experience functions
Once your account is connected, let's start experiencing more functions.‌
Get Current Account
return Promise<Array[String]>
If wallet can not be found, return [] instead of throw Error
window.ethereum.request({ method: 'eth_accounts' }).then(accounts => {
  if (accounts[0]) {
    // Do something with accounts
  } else {
    // Wallet not found
  }
})
Check wallet whether exists or not
return Promise<{data: Boolean}>
window.ethereum.request({ method: 'has_wallet', params: ['ronin'] })
// Example
window.ethereum.request({ method: 'has_wallet', params: ['ronin'] }).then(() => {
  // Wallet Exists
}).catch(e => { 
  // Wallet not found
})
Sign
return: Promise<Signature | RPC: 2.0>
// Example Sign 
const signature = window.ethereum.request({
    method: 'eth_sign',
    params: [
     {
        "to": "string",
        "gas": "string",
        "gasPrice": "string",
        "value": "string",
        "data": "string",
        "nonce": "string"
     }
    ]
});
Transfer
return Promise<hash>
window.ethereum.request({
  method: 'eth_sendTransaction',
  params: [
    {
      'to': 'string',
      'gas': 'string',
      'gasPrice': 'string',
      'value': 'string',
      'data': 'string',
      'nonce': 'string'
    }
  ]
})
